Genotype 3: What It Means for Hepatitis C and Your Treatment
Genotype 3 is a common form of hepatitis C virus (HCV) that affects the liver and changes how doctors pick treatment. Compared with other HCV types, genotype 3 can cause faster liver fat buildup (steatosis) and a higher chance of cirrhosis and liver cancer if left untreated. That makes early testing and proper treatment more important.
How do you know if you have genotype 3?
You need an HCV RNA test that includes genotype testing. Doctors usually test with a blood sample to confirm active infection and identify the genotype. If you have risk factors—past intravenous drug use, blood transfusion before 1992, or tattoos done in non-clinical settings—ask your provider for testing. Many people with HCV feel fine for years, so testing is the only way to know.
Treatment has improved a lot.
Direct-acting antivirals (DAAs) like sofosbuvir combined with other agents often cure genotype 3 in most patients. Your doctor will choose the exact drug combo and length of treatment based on whether you have cirrhosis, prior treatment, and any other health problems. People without advanced liver disease can often finish 8 to 12 weeks of treatment. Those with cirrhosis or past treatment failures may need different regimens or longer courses. Cure rates now commonly exceed 90% with the right therapy.
Before starting treatment, your doctor will check liver damage using blood tests, imaging, or a FibroScan. They will also review other medicines you take—drug interactions matter. If you have hepatitis B or HIV co-infection, treatment plans change and need close monitoring. Vaccines for hepatitis A and B are often recommended if you are not immune, because co-infection can worsen liver disease.
Lifestyle steps matter while you treat your liver. Cut back on alcohol, control weight, avoid unregulated supplements that can hurt the liver, and follow a balanced diet. Smoking and excess alcohol raise risks even after the virus is cured. If you drink, tell your provider—there are safe steps to take, and some people need extra monitoring.
After treatment, blood tests check viral clearance and liver health. Even after cure, people with advanced fibrosis should keep getting periodic liver checks for cancer. Talk to your doctor about long-term follow-up.
If you worry about access or cost, ask your clinic about patient assistance programs and generic options used safely under medical supervision. Never try to self-treat or buy prescription drugs without a proper prescription and medical guidance.
